In the figure, a Mass m1 is connected to another mass m2 by a massless string over a frictionless pulley, when m1 slides on a surface by effecting of m2. M1= 2kg. M2= 1.5 kg

if the kinetic friction coefficient between m1 and the surface is 0.35

1- draw the free-body diagram of the forces acting on m1

2- calculate the acceleration of m1 on the surface.

what is the question?

answer; i believe the correct answer is (40,000 j) good luck

answer; how far out of place which the object finished relative to the starting location;

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
